In case of an UNWRAP failure, the binding returns -1, which is truthy.

_snprintf() doesn't zero-terminate the buffer on overflow. Use the hand-rolled
version that lives in src/node_internals.h.

Add a clear warning about known issues with the module and a pointer to the
GitHub issues list for the module. Describe some of the biggest known issues
with the module.

Closes #3201.

Somehow this got downgraded in the last v0.6 merge.  Very strange.

This is an incredibly useful thing to know about, and it
will likely never change.  I can't remember why we
didn't ever document it, and people keep suggesting we
do so.

Regarding discussion in #3198.  Passing the worker as an argument
to an event emitted on the worker is redundant, and an unnecessary
break in consistency vs the events on the ChildProcess objects.

It was removed from 'exit', but 'listening' and others were
overlooked.  This corrects that oversight.

It's too slow.

Make the configure script warn the user about the lack of an acceptable
C compiler on the system.

Fixes #3209.

Fixes #3223.

See: http://tools.ietf.org/html/rfc6585

Fixes #3217.

test: fixes due to new cluster api.

- changed worker `death` to `exit`.
- corrected argument type expected by worker `exit` handler.

test: more tests of cluster.worker death

cluster: fixed arguments on worker 'exit' event

worker 'exit' event now emits arguments consistent with the
corresponding event in child_process module.

The crashes in debug mode after adding Locker are *not* caused by
Locker. Locker is merely exposing issues that already existed. Some of
these issues have since been fixed in 70635753.

Move parsers.free(parser) to a single function, which also
nulls all of the various references we hang on them.

Also, move the parser.on* methods out of the closure, so that
there's one shared definition of each, instead of re-defining
for each parser in a spot where they can close over references
to other request-specific objects.

Regarding #3199 and #3179 and issues seen in production.
Hopefully this fixes them.

* Upgrade npm to 1.1.21

* uv: Add support for EROFS errors (Ben Noordhuis, Maciej Małecki)

* uv: Add support for EIO and ENOSPC errors (Fedor Indutny)

* windows: Add support for EXDEV errors (Bert Belder)

* http: Fix client memory leaks (isaacs, Vincent Voyer)

* fs: fix file descriptor leak in sync functions (Ben Noordhuis)

* fs: fix ReadStream / WriteStream double close bug (Ben Noordhuis)

This way it doesn't die when running as root.
